PAVING- BLOCK.

SPECIFIGATION forming part of Letters Patent No. 674,672, dated May 21,1901.

To ctZZ whmn it may concern/.-

Be it known that I, REUBEN D. CULVER, of the city of Veedersburg,Fountain county, State of Indiana, have invented certain new and usefulImprovements in Paving-Blocks, of which the following is a full, clear,and eX- act description, reference being had to the accompanyingdrawings, forming a part hereof.

This invention relates to paving-blocks; and it consists of the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

The object of this invention is to provide an improved paving-blockhaving suitable passages formed in its vertical faces to permit thepassage of the sand, cement, or other material which may be used as afiller in order to form a more perfect joint.

' Figure 1 is a perspective view showing two paving-blocks constructedin accordance with the principles of my invention. Figs. 2 and 3 areside elevations showing different sides of the paving-block. Fig. 4 isan end view of two adjacent paving-blocks.

In constructing a paving-block in accordance with my invention I formthe body 1 substantially rectangular in shape, and in one of thevertical faces are formed two parallel grooves 2, which divide the faceof the block into three divisions of substantially equal area. Thecentral division 3, as shown in Fig. 4, projects farther from the bodyof the block than do the side divisions t, so that when twopaving-blocks are laid adjacent to each other their central divisions 8bear against each other, while the divisions 4 are at a slight removefrom each other. The horizontal grooves 2 are connected by verticalgrooves 5, formed at suitable intervals across the projecting division3, thereby permitting the passage of the sand or other material that maybe used from the upper side to the lower side of the block. A horizontalgroove 6 is formed in the upper division at, and a corresponding groove7 is formed in the lower division. The opposite side of the block ispreferably formed with three divisions, of which the side divisions areidentical with the divisions 4 and are provided with the horizontalgrooves 8, corresponding to the grooves 6 7.

Instead of the projecting portion 3 I provide a number of projections orelevations 9,

rigid with the face of the block and extending therefrom a distanceequal to that of the projection 3. These projections are at a slightremove from the side divisions of the face of the block and leavepassage-ways 10, corresponding to the grooves 2 formed in the oppositeface of the block. These projections are also separated a slightdistance from each other, permitting the filler to pass'between them toreach the lower side of the block. In the form shown in the drawings Ihave used letters for the elevations described; but it is manifest thatany other form may be used without departing from the scope of myinvention, and I do not desire to be limited to any exact construction.In either case the projections will perform the same function as theprojecting division 3, while at the same time the material may readilypass to the lower side of the block to fill in the spaces whereverneeded.

In Fig. t I have shown two paving-blocks arranged adjacent to eachother, with the elevations 9 on one block bearing against the projectingdivision 3 on the other block and holding the side divisions out ofcontact with each other, leaving a space 11 at each side between the twoblocks. The grooves 8 are in alinement with the grooves 6 and 7, and vthe passages 10 are in alinement with the grooves 2, forming continuouspassage-ways from one endto the other of the blocks. The sand or othermaterial which may be used is poured between the paving-blocks into thespaces 11, from which it passes into the passage-ways formed by thegrooves -2 and the passages 10, and thence to the lower side of theblock to fill in wherever it is needed.

I claim l. A paving-block having two horizontal grooves formed in one ofits vertical faces and dividing the face of the block into threedivisions, of which the central division projects farther. from the bodyof the block than the side divisions, and vertical grooves extendingacross the central division and joining the horizontal grooves,substantially as specified.

2. A paving-block having one of its vertical faces divided into threedivisions, and a series of elevations in the central division whichextend farther from the body of the block than do the side divisions,substantially as sion and joining the horizontal grooves 2, and I0specified. grooves 6, 7 formed in the said side divisions,

3. A paving-block having the horizontal substantially as specified.grooves 2 formed in one of its vertical faces, In testimony whereof Iafifix my signature 5 thereby forming a central division 3, and the inpresence of two witnesses.
